On April 10, 1940, British submarine HMS Tarpon and its crew of 50 were sent to Norway to intercept Nazi merchant vessels. They were was never heard from again. Now, after 76 years, the sub has finally been found. An investigation of the remarkably well preserved vessel shows it didn’t go down without a fight.

Here is footage showing a Russian Navy submarine attacking ISIS positions in Raqqa, Syria by launching missiles from the submarine itself. The Kalibr cruise missiles were launched from the Rostov-on-Don submarine, a Kilo-class diesel electric submarine, in the Mediterranean. It’s the first time Russia had launched…

Yachts are for chumps. People who really know how to spend their money get submersible yachts from Migaloo, a mysterious company that offers five different models of underwater palaces. But true evil villains just go for the Migaloo’s crown jewel: Kokomo Ailand.

The idea to build a plane that turns into a submarine is not new. However, the mission to build an unmanned variation of such a vehicle is rather 21st-century. Boeing actually already has a design ready.

Submariners are essentially living in an environment that should immediately kill them. In the early days of submarines, it would often find a way to do just that. One particularly horrible way involved a strange phenomenon that happened when sea water hit submarine batteries.

If we're ever going to explore the only celestial body in our solar system with surface bodies of liquid, we're going to need a sea-worthy vehicle. Luckily, NASA is all over the niche space submarine market.

If you ever find yourself staring out at the sea, thinking, "Holy shit, I have way too much money. I should blow some of it on a personal submarine," the Deepflight Super Falcon Mark II is here to part you from that troublesome cash.

Impressive photo of the giant tubes that house four of the 24 Trident II D5 Submarine Launched Ballistic Missiles (SLBM) carried by Ohio-class nuclear submarines. 14 of these submarines travel for months underwater, carrying fifty percent of all the active thermonuclear warheads in the US arsenal.

The size and thickness of the Antarctic ice sheet acts as a barometer for global health but figuring out exactly how much frozen water is sitting atop the southern pole is difficult. Satellite results are often obscured by layers of snow and ice core boring requires people to brave the extreme cold to collect them.…

Looks like North Korea's engineers have been hard at work brushing up on their obsolete Soviet-era technology. Because after acquiring 10 discontinued Soviet subs, everyone's favorite little warmongering-dictatorship-that-could has finally rendered the outdated ballistic vessels seaworthy—and it only took them 21…

The Axis war effort throughout the first half of the 1940s led to some incredible advances in submarine technology. That includes the anaerobic Walter turbine—a newfangled engine that didn't need oxygen to work. Even more incredible, these discoveries were not entirely new, but in fact more than 60 years old—the…

America's isn't the only military to rely on heavy-lift transport vessels, the unusual class of utility ship that helped ferry the crippled USS Cole home for repairs. Russia has just released a series of photos documenting the slow return trip to the Zvezdochka shipyard for a pair of its Akula II-class submarines, the …

Russia isn't the only nation launching a nuclear sub hunter after two decades of development. The UK recently rolled the third of seven £1 billion Astute Class nuclear submarines, the HMS Artful, out of its cavernous dry dock for a year of demanding sea trials and a quarter century of service beneath the seas.

Check out Manatee — a concept personal submersible vehicle designed by Eduardo Galvani. Designed for safe and comfortable subaquatic explorations, the sub can be controlled by anyone who knows how to operate a joystick and a touch screen control panel. Jacques Cousteau — eat your heart out.
